Computer shock absorbing platform

Abstract

The invention provides a computer shock absorbing platform. The computer shock absorbing platform comprises an equipment mounting frame, at least four variable damping shock absorbers and a shock absorbing device. The variable damping shock absorbers are evenly arranged between the equipment mounting frame and the shock absorbing device. Computer equipment is arranged on the equipment mounting bracket. The top ends of the variable damping shock absorbers are connected with the bottom of the equipment mounting frame. The bottom ends of the variable damping shock absorbers are connected with theshock absorbing device. An acceleration sensor is arranged in the position, close to each variable damping shock absorber, of the bottom of the equipment mounting frame. By cooperating the variable damping shock absorbers with the shock absorbing device, the damping can be adjusted in real time within the working frequency range. The anti-vibration performance of a computer can be effectively improved, damping is increased in an amplification area to reduce resonance, and damping is decreased in a vibration isolation area to reduce the vibration transmission rate. When the center of gravity of the equipment does not match the layout centers of the shock absorbers, the stability of the equipment in the vibration process can be ensured by controlling the output of each variable damping shock absorber.

Description

technical field [0001] The invention relates to the field of computer vibration reduction, in particular to a computer vibration reduction platform. Background technique [0002] In vehicle-mounted, airborne and ship-borne states, the computer will be frequently subjected to various types of exciting forces, and the damage caused by the computer in the vibration environment is mainly manifested in the following two aspects: (1) at a certain excitation frequency Resonance occurs under the environment, resulting in physical damage of components or electrical connection disconnection, poor contact and other problems; (2) In the vibration isolation area, under long-term vibration conditions, it is easy to cause fatigue damage and solder joints to the electrical or structural parts of the computer. Falling off, loose screws, etc. [0003] At the same time, based on the light and thin design requirements of the product, the overall strength of the product itself decreases, which ...

Problems solved by technology

[0004] The traditional shock absorbers commonly used in reinforced computers are generally passive shock absorbers, which cannot change the damping within the operating frequency range, that is, increase the damping in the amplificatio
